Implementations§

source§

impl FnDecl

source

pub(crate) fn self_type(&self) -> Option<SelfTy>

source§

impl FnDecl

source

pub(crate) fn print<'b, 'a: 'b, 'tcx: 'a>( &'a self, cx: &'a Context<'tcx>, ) -> impl Display + 'b + Captures<'tcx>

source

pub(crate) fn full_print<'a, 'tcx: 'a>( &'a self, header_len: usize, indent: usize, cx: &'a Context<'tcx>, ) -> impl Display + 'a + Captures<'tcx>

  • header_len: The length of the function header and name. In other words, the number of characters in the function declaration up to but not including the parentheses. This is expected to go into a <pre>/code-header block, so indentation and newlines are preserved.
  • indent: The number of spaces to indent each successive line with, if line-wrapping is necessary.
source

fn inner_full_print( &self, line_wrapping_indent: Option<usize>, f: &mut Formatter<'_>, cx: &Context<'_>, ) -> Result

source

fn print_output<'a, 'tcx: 'a>( &'a self, cx: &'a Context<'tcx>, ) -> impl Display + 'a + Captures<'tcx>

impl PartialEq for FnDecl

source§

fn eq(&self, other: &FnDecl) -> bool

1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
